[asterisk-addons-commits] russell: trunk r442 - in /trunk: asterisk-ooh323c/config.h chan_mobile.c

[SVN commits to the Asterisk addons project]

Author: russell
Date: Fri Sep  7 21:07:45 2007
New Revision: 442

URL: http://svn.digium.com/view/asterisk-addons?view=rev&rev=442
Log:
* Use sizeof() to specify the buffer size instead of a constant
* Remove a couple calls to memset before strncpy, as it is not needed
* Replace a couple uses of strncpy with ast_copy_string.  Note that one of
  these was potentially dangerous.  The length limit passed was actually the
  length of the *source* string, which had a larger buffer than the destination.
